Title: IPOD AMP
Post by: mahavishnu on December 19, 2006, 12:21:19 PM: drives my Numark very well. opamp OPA2134 was used here. and i'll be experimenting with OPA2132 on the next 2. the CMoy's very clean and LOUD at just 9oclock. very tight bass response and gives this virtual like 3d soundstage on my DJ cans. i havent tested it on standard earphones, i prolly wont. i ll try it on in-ears by the end of the year, if i feel like buying ERs and have earmolds (only 300 pesos for earmolds, cost alot in the states!). ive yet test it on the grado sr80 as well.

here's the bare amp (thnx sir arnold!), its actually half the size of the altoids, so im looking for a smaller enclosure. but the next 2 will definitely be housed in altoids.

(http://i70.photobucket.com/albums/i120/severthee/IMG_9093.jpg)

getting it in the altoid tin wasn't easy...

ive to take out the input/output jacks, volume pot, and extend the battery clip. and you need lots of patience to solder, little wires to their right contacts. then you apply shrink tubes to avoid electrical tape goo. put hole on the tin using a nail and make it big with screw driver (manual).

put insulator on the inside of the tin just to make sure that solder under the pcb dont short.
always test that everything's working, you might break a wire or sumthing in the process. so always check.

i put a foam to separate the battery from the pcb, to avoid it from touching delicate caps, resistors, specially the opamp, in case the tin gets shaky...
(http://i70.photobucket.com/albums/i120/severthee/IMG_9097.jpg)
energizer should last 3 days.. im planning to series another clip or a dc source...

i used a spare guitar dome knob for the volume pot
(http://i70.photobucket.com/albums/i120/severthee/IMG_9098.jpg)
tested on closed dj cans.
finally.. my irezumi ipod's complete.

bliss on a DIY amp :yes: i ll stop making when i get xin supermicro, portaphile or ray samuels. i'll jump to a hybrid tube/SS headphone amp. DIY ofcourse

message me if you wanna audition.. ;)

RE: Sonic T-amp
Thanks. It does run on batteries which, they say, gives a warmer sound than when plugged. However, the audio out are clips rather than jacks. :)

That means GAS... :-o
Wala pa po ako pondo para sa mga mahal :money: na amps... :cry:
Kaka upgrade ko pa lang po kasi ng earphones ko from A4tech earbuds to Soundmagic ES18 to Sony XB400...

Tsaka na pag may matino na akong work... 8-)
Pero sa ngayon, just to experience good sound sa hindi masyadong malaking gastos... :x

Kasi kung bibilhan ko ng amp na Fiio E11 yung 2gb iPod Nano gen 1 na gamit ko, bibili nalang ako ng mp3 ni Sony, malakas naman bayo nun :nosebleed: kesa bumili or gumawa pa ako ng amp... XD

At kumalat merchandise kahit sa tpc at sulit. Ngayon may mga dedicated headphones stores nadin gaya ng sa galleria.
Nag quit ako dahil di ko na naeenjoy music. Instead na pakinggan mo kahulagan ay pinupuna nalang quality, PRAT, decay, soundstage etc

I always thought my listening experience would revolve around stock earphones hanggang nakasubok ako ng A4tech na bumabayo ng bass at naka enhance ng highs sa mga songs ng player ko.nung nagawa yun Earphones/headphones thread na yan,nakita ko yung posts mo at iba ibang brands.out of curiosity,nag test ako ng iba ibang demo units.ayun,nangati na tenga ko kakahanap ng magandang in-ears.biglang pumasok yun idea ng pag amp dahil naging locally available na nga yung FiiO.i still havent tried the "boutique" amps,baka lalo na kong malunod sa bisyo hehe.
